Whereas most builders depend on simplified spreadsheets or generic LCOH calculators, Verdigy is betting on a extra granular, system-integrated strategy. At a current Power Information webinar, Dr. Karen Das, simulation software program lead at Verdigy, offered Energize, the corporate’s digital twin platform designed to simulate inexperienced hydrogen ecosystems with excessive constancy and operational realism.
The hydrogen financial system’s progress hinges on infrastructure optimized for variability—throughout geographies, power markets, and plant configurations. In accordance with Das, the usual follow of modeling electrolyzer efficiency as a static asset inside a set renewable enter is inadequate for contemporary challenge design.

Verdigy’s critique of standard fashions facilities on their lack of ability to seize the nuances of dynamic operation. Whereas most fashions assume full-load hours and uniform renewable enter, Energize elements in real-time intermittency, matching renewables to electrolyzer response on an hourly foundation. This permits customers to simulate how effectivity fluctuates beneath variable load circumstances—a identified problem for hydrogen builders in search of to stability plant utilization with grid economics.
As an illustration, Verdigy’s system can mannequin an electrolyzer working at simply 5% capability after which ramping again to 100%, whereas accounting for system-wide impacts on balance-of-plant elements reminiscent of compressors, rectifiers, and thermal programs.
Das underscored that Energize just isn’t restricted to modeling a single electrolyzer unit; it builds a digital twin of your entire hydrogen worth chain—from era and storage to battery buffers and grid interconnection. This strategy contrasts sharply with typical challenge growth workflows, which regularly mannequin these parts in isolation.
The platform integrates over 40 design parameters, together with battery round-trip effectivity, hydrogen storage capability, and incentive timing. Extra critically, it permits customers to experiment with site-specific eventualities—adjusting for locational marginal pricing (LMP), photo voltaic era profiles, or market publicity over 20- to 30-year asset lifespans. In an surroundings the place the LCOH is commonly dictated by electrical energy prices, the flexibility to simulate seasonal and hourly electrical energy pricing can shift challenge economics considerably.
Past its technical claims, Verdigy positions Energize as a multifunctional platform supporting R&D, challenge growth, and buyer engagement. Verdigy has additionally enabled stay modeling periods with shoppers—an effort to cut back funding uncertainty and validate configuration selections in actual time.
Importantly, this technique helps modular plant design at scale. Verdigy’s 20 MW items might be configured into gigawatt-scale programs, with every subsystem modeled individually and aggregated to mirror composite efficiency. This stage of element helps each system design and comparative evaluation between completely different electrolyzer stacks or storage configurations—an often-overlooked variable when assessing long-term OPEX.
The primary takeaway from Verdigy’s presentation is obvious: as hydrogen challenge complexity will increase, static fashions and generic assumptions are now not adequate. Excessive-resolution, system-wide modeling is changing into important not only for challenge design, however for operational technique, financing, and stakeholder alignment.
